uPVC Column Pipes

Used in Borewells

Natraj uPVC Column Pipes are used in borewell systems to lower the pumpsets in the casing pipe to raise water.

Natraj uPVC Column Pipes are manufactured to sustain high tensile loads subjected on it by the weight of the Submersible Pumpset and vibration generated by it while running. These pipes have heavy duty square threads along with a separate socket attached to one end of the pipe. To ensure leak proof joints high quality EPDM rubber rings are provided on both ends of the pipe.

  • Hanging of submersible pumps in Borewells/Tubewells

High Load Bearing Strength

Designed to support the suspended weight of submersible pumps and pipe strings, helping maintain dependable performance in deep borewell installations.

Strong Threaded Joint System

Precision threaded joints help connect pipe sections securely, supporting better alignment, reduced leakage risk and safer pump lowering.

Efficient Water Lifting Flow

Smooth internal surfaces help reduce friction loss, enabling steady water lifting from submersible pumps to the surface delivery line.

Corrosion Free Borewell Use

uPVC resists rust and corrosion in underground water conditions, making it suitable for long term borewell pumping applications.

Lightweight Pump Installation

Lightweight pipe sections are easier to handle, join, lower and remove during submersible pump installation and maintenance.

Durable Long Term Service

Built for dependable borewell operation, these pipes support continuous water lifting across domestic, agricultural and institutional use.
